Sensor setting via teach button
 The sensor is factory-adjusted for maximum operating range.
Recommendation: teach only if the desired objects are not reliably detected.
 Prior to teaching:
Clear the light path to the reflector!
The device setting is stored in a fail-safe way. A reconfiguration following voltage
interruption or switch-off is thus not required.
Teach for 11% sensor sensitivity
(full single bottles or tape with thickness > 20μm)
 Press teach button until both LEDs flash simultaneously.
 Release teach button.
 Ready.
After the teaching, the sensor switches when about
11% of the light beam are covered by the object.

Sensor adjustments via the multifunction input (pin 2)
Prior to teaching: Clear the light path to the reflector!
The device setting is stored in a fail-safe way. A reconfiguration following voltage interruption or switch-off is thus not
required.
The following description applies to PNP switching logic!
Signal level LOW  2V
Signal level HIGH  (UB-2V)
With the NPN models, the signal levels are inverted!

Locking the teach button via multifunction input (pin 2)
A static HIGH signal ( 20ms) at the teach input
locks the teach button on the sensor if required,
such that no manual operation is possible (e.g.,
protection from erroneous operation or manipulation).
If the teach input is not connected or if there is a
static low signal, the button is unlocked and can
be operated freely.
